The Hoenn region is evolving in this new trailer for Pokemon Omega Ruby and Alpha Sapphire.

The combat-based Mega Evolutions from Pokemon X and Y are back and have gone on to the Hoenn region in Pokemon Omega Ruby and Alpha Sapphire. This new trailer showcases all of the revamped areas along with the Nintendo 3DS-revamped looks of all the starter Pokemon. We get to see Mudkip, Torchic and Treecko as they evolve into their third forms. Even better, we get to see them get big and nasty as we watch their third forms Mega Evolve into brand new Pokemon.

Pokemon Omega Ruby and Alpha Sapphire will be coming out exclusively for Nintendo 3DS on Nov. 21. Buying Omega Ruby or Alpha Sapphire early will give you a free download of Diancie, the mysterious rock and fairy type Pokemon that is the main focus of the upcoming Poke-film, 'Diancie and the Cocoon of Destruction.' On top of this, Diancie can Mega Evolve.
